She ran to signal them, forcefully waving her arms and crying for help as they touched down on a nearby soccer field.

“I’m helpless. I don’t have a home, don’t have anywhere to live. I don’t have furniture, no bed, no clothes,” Sandoval, 47, told Reuters.

Hundreds of villages, isolated by power outages, impassable roads and downed telephone lines, are being helped by helicopter teams from the U.S. Army’s First Armored Division’s Combat Aviation Brigade and the 101st Airborne Division’s “Dustoff” unit.

Daily missions are flown out of the Roosevelt Roads Naval Station in Ceiba, which was closed in 2004 but is now being used by the Army, Air Force, Marines and Navy.

“It hurts because I remember how it used to be, and now it’s completely different,” said Sergeant First Class Eladio Tirado, who was born and raised in Carolina, Puerto Rico. After not visiting for roughly five years, he returned home in a Blackhawk helicopter.

“Everything is so much gone. The vegetation, everything is brown, everything is dead.”

On a recent mission over Luqillo, Tirado asked the pilots to fly over his family’s home because he had been unable to reach them by phone. The helicopter circled the house. No one was there, but Tirado was confident the message would reach his family: he’s here and he’s helping.

Media reports led crews to the village of San Lorenzo, which had received no federal assistance since the hurricane. Dozens of people pressed against a fence to watch helicopters land, anxiously waiting for food and water.

Crews are also transporting people to emergency centres and mapping open roads so trucks can make deliveries.

HOPE FROM ON HIGH

Rooftop messages like one near Humacao come through loud and clear. “HELP USA PLEASE P.R.”

Near Ciales, as Blackhawks from the 1st Armored Division flew over, people on a rooftop reached toward the sky to signal they needed water.

As helicopters scouted the island’s mountainous interior one recent Saturday a woman held a jug in the air.

They circled above houses built on top of mountains to find a level field to unload their precious cargo. One field looked open and a Blackhawk came within eight feet of the ground, but it could not land.

The crew soon found another needy community, Verde de Comerío, where it was able to land.

Villagers quickly lined up to help soldiers pass food and water to a crowd. One woman hugged Pilot Chris Greenway to thank him for water. In less than 10 minutes, hundreds of bottles of water were given to families, emptying the helicopter.

This village also needed medicine, and families with babies had no way of getting basics. Diapers and formula have become luxury goods. But every village asks for water.

The lack of potable water is slowly choking these villages and helicopters can only carry so much. Every trip leaves some who get nothing.

The crews can only hope they can return soon enough to make a difference.

“This island will never stop,” Tirado said. “People will rebuild, we will continue forward, and they’re going to see a better tomorrow.”
